Soon after the Lombard conquest (568 A.D.) the area of the late antiquity necropolis maintained its funerary role and a zone, probably fenced-in, was reserved to three tombs containing the remains of an aristocratic family group, the “wealthy burials” (4). They can be dated between the end of the VI and mid-VII centuries and are of three different kinds: one casket is in pebbles bound by mortar and is daubed with plaster and painted; the structure of the second burial is in bricks, pebbles and stones; the third is composed of reused Roman stone slabs.
The arrival of Lombards in Seprio brought about changes in buildings which remained unaltered until the XI century.

During the VII century the first nucleus of the monastery is believed to be established. The archaeological excavations, in fact, discovered the foundations of a funerary oratory, now no longer visible, containing the burials of female individuals, maybe the first nuns.
